Flexibility is a major selling point of Hamilton Beach's Big Mouth Duo, our best value food processor. The large bowl can hold a generous 14 cups, and there's a smaller bowl that can hold five cups. The lid and food chute are tough to put together, but, once assembled, the processor is fairly easy to use. The parts nest in each other, so it's good for tight spaces. But — caveat — this machine was one of the noisiest we tested.
